I don't know your particular situation, but if you create an LV, it will
normally use the first PV. Until the first PV is used, it won't allocate
from the next PV. This is only true if you use linear LV. If you use
stripes, that allocation would be completely different.
I don't think LVM remembers the last used PV for allocation to use any
kind of round robin allocation among different lvcreates. Hope that
answers your mystery.
Thanks, Malahal.
